Borrowed $1600 from my friend. Apart from this placed gold as collateral and got $250. Altogether with hope of returning the borrowed amount and taking the gold back started to play dice after a long. At the beginning it went good, and when my profit reached $200 started to fail. Once I began to loss I was out of my control. Within minutes everything went out of my control, my mind didn't had the ability to think. I just doubled the bets consecutively. Ended with a loss. Now I was in a situation to repay my friend the borrowed amount. Please don't borrow and spend on gambling, it might give an earning, but that mostly leads to suffering. 
Part of the rules of gambling, do not borrow money to stake. You made so many mistakes here including gambling irresponsibly(i am not trying to insult you). You should try to use gambling disciplines once you realise that you start losing. You shouldn't be blackout because you lose, relax and observe for sometime. I know it was a though decision for you which can never be undone and I'm sure you have leaned your lesson the hard way.
My little advise is that don't try to gamble in order to pay your friend back because it may not end well.
